Halton FDB2 fire dampers are type-approved class • Blades contain silicone (effective up to 300 ºC) A0(A60) fire and gas dampers for use in offshore, marine for low leakage in normal conditions and thermal and navy ventilation systems. The FDB2 can be installed expansion graphite seals (effective from 150 ºC) in rectangular or circular ducts. All fire dampers have a to increase tightness even up to 50% in a case of fusible link and they prevent the spread of fire and gases fire. Tightness substantially better than NORSOK within the ventilation ductwork. When the blades are in requirements.
